Investigating Label Bias in Beam Search for Open-ended Text Generation

22 May 2020 Liang Wang Jinlong Liu Jingming Liu

Beam search is an effective and widely used decoding algorithm in many sequence-to-sequence (seq2seq) text generation tasks. However, in open-ended text generation, beam search is often found to produce repetitive and generic texts, sampling-based decoding algorithms like top-k sampling and nucleus sampling are more preferred...
